Ok guys, there seems to be a lot of assumptions about the new core set. In my travels to various stores today, here is what I have discovered:
Target DOES have the core set, but at the 3 stores I visited near me, I couldn't convince anyone to fork it over early (a tactic that usually works with new nerf blasters). Apparently the boxes have a street date of 9/4 plastered all over them.
Other retailers MAY have them. Toys'r'Us for example, wouldn't confirm that they have it, only that new Star Wars stuff will be available at midnight.
THERE IS NO EVIDENCE WHATSOEVER THAT THIS SET IS EXCLUSIVE TO TARGET. LGS' may be able to order them after the official reveal, but ultimately the only thing we know is that target will/does have them. Everything else is rumor. Take a breath and find out tomorrow.
